Overview:For the past few weeks, revolt has been brewing in the Kingdom of Naples. The handsome Castelli is at the head of the conspiracy that wants to put an end to the reign of King Murat. To carry out his plan, he decides to infiltrate the court in order to become an intimate of the king. But his ploy works too well: he manages to enter the court thanks to his talents as a singer and very quickly seduces Queen Geneviève. But this imprudence costs him a lot. He is soon arrested by the king's men and immediately condemned to death.
